Re: lanzar opti amp specs old school stuff

thanks but i google it, oogle it, and came up with nothing. i did have a manual for my lanzar 2500 amp, but if i remember correctly it had some specs of other lanzar amps, of course when i need it most to sell some of lanzars i can't find it. i'm looking for specs for the bluish color lanzars; the sl50, sl150, 160, etc.. amps..
